| Primary | Number of Participants (Par.) With Any Recurrence of the Initial Disease, Second Primary Cancer, Contralateral Breast Cancer, or Death (Disease-free Survival [DFS]) | From randomization until date of the first occurrence of an objective disease recurrence, a second primary cancer, or death from any cause (assessed up to 6 years; 1 year of treatment, 5 years of follow-up [median of 5.3 years for final analysis]) | DFS=interval between the date of randomization and the date of the first occurrence of an objective disease recurrence, a second primary cancer, or death from any cause. The date of the event is the earliest date of the occurrence of any of the following: local recurrence (LR) following mastectomy; LR in ipsilateral breast following lumpectomy; regional recurrence; distant recurrence; contralateral breast cancer, including ductal carcinoma in situ; other second primary cancer (excluding squamous or basal cell carcinoma of the skin, melanoma in situ, carcinoma in situ of the cervix, or lobular carcinoma in situ of the breast); death from any cause without a prior event. Par. who started additional anti-cancer adjuvant therapy prior to the recurrence of their disease were to be censored. Par. who did not withdraw from the study and did not experience a specified event or death were to be censored (follow-up ongoing) at the last visit date available at which progression was assessed. |

| Secondary | Change From Baseline in Short Form-36 Version 2 (SF-36 v2) Scores for the Physical Component Summary (PCS) | Baseline, Month 6, Month 12, and every 6 months after discontinuation of study treatment for 24 months (up to a maximum of 3 study years) | The SF-36 v2 is a self-administered, health-related quality of life (QoL) metric. It is a 36-item questionnaire designed to measure 8 domains of functional health status and well-being: physical functioning, role-physical, bodily pain, general health perceptions, vitality, social functioning, role-emotional, and mental health. Each domain is scored from 0 (poorer health) to 100 (better health).The PCS score is a summary score representing overall physical health, which is derived from the 8 domain scores. As with each domain score, the PCS score ranges from 0 to 100; higher scores represent better health. Change from Baseline was calculated as the post-Baseline score minus the Baseline score. Missing post-Baseline data were imputed using the last observation carried forward (LOCF) method. The scores were analyzed using an analysis of covariance (ANCOVA) model, adjusting for Baseline sub-scale score, treatment, and country. Positive changes from Baseline indicate improvement. |

| Secondary | Number of Participants With Hematology Values Outside the Reference Range for the Indicated Parameters | At Baseline and every 3 months thereafter up to Month 12/Early Withdrawal Visit | The hematology parameters assessed were: basophils (Bs) in giga (10\^9) per liter (GI/L) and in percentage (%), eosinophils (Eo) in GI/L and %, hematocrit, hemoglobin, lymphocytes (Lmph) in GI/L and %, monocytes (Mono) in GI/L and %, platelet count, Red Blood Cell (RBC) count, total neutrophil count (TNC) in GI/L and %, and White Blood Cell (WBC) count. The Baseline (BL) value is the last available pre-treatment result recorded. "Any post-Baseline value" was based on results recorded at any scheduled or unscheduled post-Baseline visits. The prevalence of values lying outside the reference (ref.) range (high or low) is presented for BL and "any post-Baseline" (APBL) visit. Two participants were randomized to placebo but received lapatinib; therefore, they are included in the lapatinib treatment arm. Data for the primary analysis (conducted in 2011) are reported. |
| Secondary | Number of Participants With Clinical Chemistry Values Outside the Reference Range for the Indicated Parameters | At Baseline and every 6 weeks thereafter up to Month 12/Early Withdrawal Visit | The clinical chemistry parameters assessed were: alanine amino transferase (ALT), albumin, alkaline phosphatase (ALP), aspartate amino transferase (AST), bicarbonate, blood urea nitrogen (BUN), bone alkaline phosphatase (Bone ALP), calcium, chloride, creatinine, creatinine clearance (Cr. Clearance), creatinine clearance estimated (Cr. Clrnc. est.), glucose, potassium, sodium, total bilirubin (Total Bln), total protein, urea, and uric acid. The Baseline (BL) value is the last available pre-treatment result recorded. "Any post-Baseline" value was based on results recorded at scheduled or unscheduled post-Baseline visits. The prevalence of values lying outside the reference (ref.) range (high or low) was presented for BL and "any post-Baseline" (APBL) visit. Two participants were randomized to placebo but received lapatinib; therefore, they are included in the lapatinib treatment arm. |
| Secondary | Number of Participants With Non-laboratory Toxicities of the Indicated Toxicity Grades | From the first dose of study treatment up to 12 months | Non-laboratory toxicities are defined as adverse events (AEs). The number of partcipants with any treatment-emergent AE of the indicated toxicity grade are summarized. Toxicity grading was according to the National Cancer Institute Common Terminology Criteria for Adverse Events Version 3.0 as follows: Grade 1=mild; Grade 2=moderate; Grade 3=severe; Grade 4=life threatening; Grade 5=death. The events that were not given a toxicity grade are categorized as "Not Applicable." |
| Secondary | Number of Participants Experiencing Primary or Secondary Cardiac Events | From the date of randomization up to 12 months | A cardiac event is classified as a primary cardiac endpoint (PCE) or a secondary cardiac endpoint (SCE). PCE is defined as: cardiac death (cardiac death due to heart failure, myocardial infarction, or arrhythmia;or probable cardiac death defined as sudden, unexpected death within 24 hours of a definite or probable cardiac event); severe symptomatic congestive heart failure (CHF) (as per New York Heart Association \[NYHA\] Class III or IV and an absolute decrease in left ventricular ejection fraction \[LVEF\] of more than 10 percentage points from Baseline and to a left ventricular ejection fraction \[LVEF\] value below 50%). SCE is defined as asymptomatic or mildly symptomatic cardiac events (NYHA Class I or II) and a significant decrease in LVEF, defined as an absolute decrease in LVEF of more than 10 percentage points from Baseline and to an LVEF value below 50%. |
| Secondary | Number of Participants With the Indicated Electrocardiogram (ECG) Findings | Screening and Month 12/Early Withdrawal Visit | 12-lead ECG measurements were taken at Screening and at study conclusion/withdrawal. The number of participants with normal, abnormal clinically significant (CS), and abnormal not clinically significant (NCS) ECG findings, as classified by the investigator, were summarized. Participants with missing values were categorized as missing. Data for the primary analysis (conducted in 2011) are reported. |
